k8s部署nacos2.0.3出现tried: server is DOWNnow, detailed error message: Optional[Distro protocol XXXX

问题描述，在k8s中部署nacos2.0.3，客户端出现出现下面错误信息：

tried: server is DOWNnow, detailed error message: Optional[Distro protocol i

yaml脚本部署设置了nacos部署MODE为mode，但是通过控制台日志打印还是Cluster mode

Running in cluster mode, All function modules

nacos2.0.3需要开放多个端口，在yaml文件中只添加了8848和7848端口，其他端口为加上，导致错误出现
